just got back from the ford fair and i treated my S2 2 a new -31 act as mine was poor as piss...

i fitted it there and then and drove it home 180miles back to Doncaster. I wound the pre-load in just enough so i could pull it over the wastegate. It boosted straight away and very smoothly 2, however it went 2 18psi then held 16ish, but my turbo sounds like a jet plane taking off, its very loud so on the off chance i didnt let it go past 10psi incase of over-boost...

its chipped with all the usual sensible mods, and when i arrived home the tailpipe was a light black/grey....

So does it sound like the turbos gonna go pop or is it normal for it 2 b loud ????
